Fix:
marker . setAttributes ( new String [ ] { IMarker . MESSAGE , IMarker . PRIORITY , IMarker . DONE , IMarker . CHAR_START , IMarker . CHAR_END , IMarker . LINE_NUMBER , IMarker . USER_EDITABLE } , new Object [ ] { task . getMessage ( ) , new Integer ( priority ) , Util . toBoolean ( false ) , new Integer ( task . getSourceStart ( ) ) , new Integer ( ( ( task . getSourceEnd ( ) ) + 1 ) ) , new Integer ( task . getSourceLineNumber ( ) ) , new Boolean ( false ) } ) ;
